Description

This is a continuation of application Ser. No. 08/278,254, filed on Jul. 21, 1994, now abandoned, which is a continuation of Ser. No. 08/032,651 filed on Mar. 17, 1993 now abandoned.

BACKGROUND OF THE INVENTION

This invention relates to a connector which is mounted on a glass plate to connect a terminal and a long conductor attached to a glass plate.

FIG. 1 shows a rear window glass 1 of an automobile. Referring to FIG. 1, the rear window glass (hereinafter referred to as a "glass plate") 1 of the automobile is provided with an antifogging resistor wire 3 printed thereon. Referring to FIG. 2, the resistor wire 3 printed on the glass plate 1 has a wide portion 5. A plate-like male terminal 7 has one end attached to the wide portion 5 by means of soldering and the other end to be connected to a female terminal formed at a top end of a wire harness 9. The wire harness 9 is connected to a battery of the automobile. Thus, the resistor wire 3 is energized by the battery through the wire harness 9, the female terminal, the male terminal 7, and the wide portion 5. The female terminal at the top end of the wire harness 9 is accommodated in a terminal accommodating chamber formed in a housing of a female connector 11, as illustrated in FIG. 2 (Japanese Utility Model Laid Open No. 78170/1981).

With the above-mentioned structure, the male terminal 7 is exposed or naked and subjected to an external force. This causes various disadvantages such as deformation of the male terminal, crack of the soldered part, and breakage of the glass plate.

SUMMARY OF THE INVENTION

In view of the above, it is an object of this invention to provide a connector adapted to be mounted on a glass plate, which is capable of reliably connecting a feeding terminal to a resistor wire printed on the glass plate without occurrence of deformation of a male terminal, undesirable release of the male terminal, and breakage of the glass plate.

In order to accomplish the above-mentioned object, this invention provides a connector for connecting a terminal and a conductor attached to a glass plate, comprising:

a first connector fixedly mounted on the glass plate, the first connector having a fitting hood bridging the conductor, the fitting hood having a first opening which opens towards the conductor; and

a second connector having a body to be fitted into the fitting hood, the body having a terminal accommodating chamber for accommodating the terminal and a second opening which allows a part of the terminal to project towards the conductor.

According to this invention, when the second connector is inserted and fitted into the fitting hood of the first connector, an elastic terminal of the second connector is brought into elastic contact with the conductor which is bridged by the fitting hood along a transversal direction.

BRIEF DESCRIPTION OF THE DRAWING

FIG. 1 is a front view of a rear window glass of an automobile;

FIG. 2 is a perspective view for describing a conventional structure for connecting a resistor wire and a feeding wire harness;

FIG. 3 is a perspective view of a connector adapted to be mounted on a glass plate according to an embodiment of this invention with a part cut away; and

FIG. 4 is a sectional view of the connector adapted to be mounted on a glass plate illustrated in FIG. 3 in a condition before a male connector is fitted into a female connector.

FIG. 5 is a perspective view of the connector of FIG. 4, showing the male connector ready to be inserted into the female connector having a fitting hood bridging a conductor affixed to the glass plate.

DESCRIPTION OF THE PREFERRED EMBODIMENT

An embodiment of a connector adapted to be mounted on a glass plate according to this invention will be described with reference to the accompanying drawings hereinafter.

FIGS. 3 and 4 show a connector 13 adapted to be mounted on a glass plate according to this invention. Referring to FIGS. 3 and 4, the connector 13 comprises a female connector 19 and a male connector 23. The female connector 19 has a fitting hood 17 bridging a conductor 15 along a transversal direction of the conductor 15. The male connector 23 is inserted and fitted into the fitting hood 17 of the female connector 19.

The female connector 19 has a bottom portion 19d provided with an insertion portion 19a which is formed at an intermediate area and extends in a longitudinal direction. The insertion portion 19a is open for insertion of the conductor 15. Thus, the insertion portion 19a defines a first opening which opens towards the conductor 15.

The fitting hood 17 further includes a second opening 17a for receiving the male connector 23, and a third opening 17b in a wall 17c opposite to the second opening 17a, the third opening 17b being smaller than the second opening 17a. A pair of attaching portions 19b are formed on both sides of the insertion portion 19a and laterally projects therefrom. The attaching portions 19b are attached onto a glass plate 1. A lock arm inserting portion 19c is integrally formed with the upper part of the fitting hood 17. The lock arm inserting portion 19c has an engaging hole 25.

On the other hand, the male connector 23 comprises a housing 23a and a flexible lock arm 27. The housing 23a has a terminal accommodating chamber 33. The flexible lock arm 27 is supported on the forward end of the housing 23a and extends in the rearward direction. It is noted here that the terms "forward" and "rearward" are used with respect to a fitting direction along which the male connector 23 is inserted into the female connector 19. The terminal accommodating chamber 33 accommodates an elastic terminal 21. The elastic terminal 21 comprises a crimp member 35 for crimping a wire 9, and an elastic contact member 31. The elastic contact member 31 is inwardly bent at its top end and again inwardly bent. Thus, the elastic contact member 31 has a first bent portion 31a and a second bent portion 31b. The elastic contact member 31 has, at its lower end, a contact portion 31c to be brought into contact with the conductor 15.

The housing 23a has a second opening 23b which allows the contact portion 31c of the elastic contact member 31 to project towards the conductor 15.

The terminal accommodating chamber 33 is provided with a flexible engaging piece 37 formed on the inner wall thereof. The flexible engaging piece 37 has a top end to be engaged with an engaging hole 21a formed on the elastic terminal 21. Thus, the elastic terminal 21 is prevented from belong released from the terminal accommodating chamber 33.

The flexible lock arm 27 has an engaging projection 29 to be engaged with the engaging hole 25 of the lock arm inserting portion 19c. The flexible lock arm 27 is further provided with a pressing portion 39 formed rearwardly of the engaging projection 29.

Referring now to FIG. 5, the female connector 19 is preliminarily attached onto the glass plate 1 to bridge the conductor 15. On the other hand, the male connector 23 accommodates the elastic terminal 21 formed at the end of the wire 9. When the male connector 23 is inserted and fitted into the fitting hood 17 of the female connector 19, the elastic contact member 31 of the elastic terminal 21 is put into elastic contact with the conductor 15 to provide electric connection therebetween. By engagement of the engaging projection 29 with the engaging hole 25, the male connector 23 is inhibited from being released from the fitting hood 17 of the female connector 19.
